As posted (as part of another topic) previously, I am in a bit of a Neighbour(s) from Hell situation (and I am sure they think I am one too....) - "typical" problems - noise (amplifier outside) including indredibly foul language of course, weed (x about 8-10 people sometimes), barbecues and fires, using my path when they have their own..... etc etc. All of which are making me feel as through my already diminished life is becoming smaller and smaller, with my thoughts sometimes overwhelmed by the situation. (I know, tragic.)
Last week, I had said something to a teenager visiting about the music - I simply asked if she had headphones (don't they all?) - mainly because the music from the amplifier from INside clashed terribly with whatever she was playing on her phone. I was then screamed at by the Neighbour (female) and told that they would "do it louder now". But then they went away for a few days. Such bliss - which I know is wrong of me.
ANYway - before they did, I happened to encounter a (male) friend/visitor - who obviosuly doesn't know that hostilities have been ramped up. I was just leaving and locking my door - which is right NEXT to their door (see notes re. path - no barrier etc etc).
He (male next door) has a lot of friends, and they all look very similar (I call them- in my head - the Reginalds), but this one must have never seen me before, as he - ah, oh no - SPOKE to me (!)
I was a wee bit "dressed up" and hair done etc, and he decided that flirtation was the best way to go - which I only really responded to by mentioning my daughter's age, and laughing at his weird attempts to chat up a much much older lady. The NDN was not asnwering the door and the "Reginald" said, "Ooh, I bet they're having sex..."
I sighed - got into my car and drove away and was gone for most of the day.
When I came back and was getting things out of my car - about 11pm - he and NDN just parked his car (I suspect drink driving was involved) and he approached me again. As I was putting the seats back up in the rear of my car (bike had been in it), he held a hand out to help me and pulled me towards him rather too closely. I again laughed it off and NDN told him to "come on, twat". (Music and noise then went on for a long time....sigh)
So, this person visited again last night, a few hours after NDNs came back from their short break. I am not SO nosey that I actually listen - but they are so loud and so close that if I set foot outside, I can hear some of what is being said whether I want to or not. I water my few plants later in the evening and just as I opened the patio doors, I heard the very same person say, "And I'm coming back to f**k your next door neighbour". 
[The house on the other side is empty, so it's not someone else.]
Cue much laughing 
, even though he sounded semi-serious....
I do feel vulnerable here (and in the wider area, I hate to say)' things like this do highlught it, because I don't really know what I can do. The difficulties with the NDNs have escalated to a sort of bullying, as they know I am by myself and no-one really even comes here (just the one friend I talked about before). At "best", I am ignored - and at worst (so far), life made difficult/NO consideration at all - and if I say anything at all, I am spoken to like shit.
I know age shouldn't be a factor, but they are I think about eight years younger than my own daughter - I am so ashamed of how this is playing out - and it must be said, find what the friend said last night quite worrying...... (almost sure it was a joke, for the laughs (again, at my expense).
I am mainly ranting (yes, I know it's AIBU), but I would be interested to hear some other views x
